A Yiddish word which sounds absolutely crude yet commonly known as the "naval" or "belly button" but is actually mistaken for meaning asshole or anus.
Noun: "When Fig woke up this morning and got into the shower he saw an assortment of nuts on the shower floor. He then realized that his pupik was sore because the naughty ninger man stuffed cashew nuts inside it."
yiddush for bellybutton or navel
Lint collected in the pupik is not attractive! It must be emptied daily...
